Abstract: A computer system has clients and servers of different object models, such as SOAP, CORBA and EJB for providing distributed application services. To connect a SOAP client to a CORBA or EJB server, a bridge 10 is used containing corresponding server and client components as well as a mapping component to map object and method requests of one type into another.

Abstract: The invention relates to a method and a scheduling system for scheduling a job, the job having at least one job requirement and being indicative of a scheduling policy of at least first and second scheduling policies, the method comprising the steps of: (a) performing a query in order to identify data processing resources matching the at least one job requirement and obtaining input data for the selected scheduling policy; and (b) selecting one of the matching resources by means of the selected scheduling policy on the basis of the input data.

Abstract: A system is described in which a local task (415) running on a local computer (400) can use a remote task (430) running on a remote computer (405). The local task (415) firstly establishes a conversation between a local data transmission agent (410) in the local computer (400) and a remote data transmission agent (420) in the remote computer (405). This conversation is assigned a handle (XmitHandle). The local task (415) can then use this handle (XmitHandle) to call tasks (430) running on the remote computer (405). Data is passed between the local task (415) and the local data transmission agent (410) by the use of a shared memory buffer. Data is similarly passed between the remote, task (430) and the remote data transmission agent (420) by the use of a shared memory buffer. The local (410) and remote (420) data transmission agent are connected together in a network which is preferably an SNA network.
